Identity and Access Management (IAM)

One of the most important AWS services for security is AWS Identity and Access Management (IAM). IAM enables customers to manage access to AWS services and resources securely. IAM is essential for defining who can access specific AWS resources and what actions they are allowed to perform on those resources.

With IAM, customers can create users and groups, assign specific permissions to them, and apply policies that govern access. IAM also supports Multi-Factor Authentication (MFA), which enhances security by requiring users to provide two forms of identification (e.g., a password and a one-time code from a mobile device) to access AWS resources.

IAM roles and policies are crucial for managing permissions effectively. For example, a role can be assigned to a specific AWS service (like an EC2 instance) to allow it to perform certain actions without requiring manual authentication. IAM policies define the permissions attached to users, groups, or roles and can be used to allow or deny access to specific resources within the AWS environment.

Understanding IAM is fundamental for building a secure AWS environment and ensuring that access controls are properly implemented to prevent unauthorized access to sensitive resources.
